Showing papers in "Remote Sensing of Environment in 1975"

TL;DR: In this paper, computer enhanced images of the Gulf Stream System in the Gulf of Mexico were obtained in synchronization with LANDSAT-1, and significant oceanic parameters identified are: the probability of forward scattering, and the ratio of scattering to total attenuation.

TL;DR: In this paper, the results for the first of the four surfaces, a savannah, are shown that the directional reflected radiation may change by ± 1% per degree change of the solar zenith angle and by ± 6% change of spectral atmospheric turbidity factor at 0.52 μm.

TL;DR: In this article, the spectral information of 26 igneous rocks in the 7.5 μm to 14 μm wavelength region and chemical compositions were analyzed under simulated daytime field conditions.

TL;DR: A new table look up scheme was designed and implemented to reduce the computation time for the classification using the maximum likelihood Gaussian decision rule and permits classification of LANDSAT imagery at least an order of magnitude faster than conventional methods without compromising accuracy or requiring special computer hardware.

TL;DR: In this article, a rough estimation of the nitrogen fixation in the Baltic is given, which is an hitherto unseen part of the nutrient budget, which has been brought to attention by the aid of remote sensing techniques.

TL;DR: It is shown that little formal training is required for obtaining quite high interpretation accuracies from multi-channel radar images of some urban scenes, and the rationale for multispectral radar is considered to be soundly based.

TL;DR: In this paper, the authors investigated the effect of three-band isoluminous transformations on additive color projection and showed that they can cause chromatic confusion unless original brightness variations are small.

TL;DR: In this article, multispectral remote sensing data were collected along the U.S. shoreline of Lake Ontario as part of the International Field Year on the Great Lakes (IFYGL) program in Lake Ontario.

TL;DR: In this paper, the authors showed that the average of the daily maximum and minimum water contents closely approximated the 24-hour average of soil water content in Avondale loam at Phoenix, Arizona.

TL;DR: In this article, the authors studied eddies on the western boundary of the Gulf Stream off the southeast coast of the United States using NOAA-2 IR data and data collected by the R/V DALLAS HERRING.

TL;DR: In this article, the use of statistical features was used to discriminate sea ice from clouds with 90% or greater accuracy, which is the state-of-the-art performance.

TL;DR: In this paper, three workers mapped part of arid central Australia according to the patterns they could discern on 5th generation Landsat I imagery and compared their patterns with the types of country as shown in the survey map.

TL;DR: Canopy temperature of irrigated grain sorghum [ Sorghum bicolor (L.) Moench ] was monitored using an infrared thermometer during short-term changes in solar radiation as mentioned in this paper.

TL;DR: It is pointed out that the “text-book” approach to multispectral photography is characterised by “in situ” spectral reflectance measurements, scientific selection of camera filters, quantitative photography, and interpretation using additive techniques.

TL;DR: In this article, multispectral scanner data covering the wavelength interval from 040-260 microns were collected at an altitude of 1000 m above the terrain in southeastern Pennsylvania Uniform training areas were selected within three sites from this flightline.

TL;DR: In this article, a cropland classifier is described that evaluates approximately registered, temporal, and multispectral digital ERTS-1 data acquired over a 14 section test site in central Iowa during 1973.

TL;DR: In this article, the correlation of soil properties and photo-tones at a number of sites in lowland England was investigated and it was shown that photo-tone is related to a lithological pattern but at one site reflects the variability of fine sand content at the surface whereas in an adjacent field it is associated with variability in surface stoniness.

TL;DR: In this article, the authors describe a geological application of multispectral photography in the Bushveld Igneous Complex of South Africa, which is characterized by in situ spectral reflectance measurements, scientific selection of camera filters, quantitative photography, and interpretation using additive techniques.

TL;DR: In this paper, the authors reported differences in radiance levels over the Red Sea in the scanner imagery from the Earth Resources Technology Satellite, now called Landsat-I. Two types of effects are observed: narrow streaks of lower radiance extending for up to 100 km leeward from islands or mountains near the shore, referred to as lee-lines; and striations of alternate darker and lighter bands, each up to I km broad.

TL;DR: The use of television as a sensor was extended when it was recognized that the spectral sensitivity of television in the blue and green spectral regions made it extremely useful for oil spill studies as discussed by the authors.
